Thanks for the interest, the bracket i designed myself from a cardboard template, made it from 3/16" steel, waterjet cut and powdercoated, the tensioner is made by "Fenner Drives", model RT3000, Automotive quality, self lubricating and 0-42 lbs. super adjustable, which most are not. Fenner also sells one like the "ICE" Tensioner, which was a light duty and not as many features, it was cheaper in price and would work fine I'm sure, as there is only about 10lbs. of tension, but not as adjustable. The technician said the RT3000 was far superior if i wanted the best. As most aftermarket tensioners are frame mounted, there was no room, but luckily there was just enough room on the swingarm and the tensioner now follows the arc of travel, worked out even better. Fenner also sells the pulleys. Almost all of the pulley manufactures use the same 6203 bearings. I used a 3" x 1 3/8" composite flat belt idler pulley for 3 months, then went to a 2" x 1.5" for 2 months. I wanted to see how it would hold up compared to the 3", as it would be spinning 50% faster, and the spyder does have very high belt speed with that big sprocket. The 2" does make a very slight turbocharger sounding whistle i notice decelerating from around 40mph to 0, but i've ran it 3 hours straight at 85mph, no heat or anything, still like new. The 2" looks better asthetically. I haven't looked at the RT's swingarm to see if it would fit, if it's close, it might, the bracket is made somewhat adjustable so it can be lined up perfectly with the belt before it's tightened. Belts definately have a tight spot, idling with the rear tire off the ground, you can see the pulley jump a little when it hits the tight spot. It wasn't in my plans, but i got talked into patenting the bracket and making 25 sets, you never know.
